I ran across a strange error I didn't have before or I didn't notice.
When I use the FMX webgmaps in Win32 and I move it to another control (changing parent), it just is blank with the blank{guid} message.
I made an easy demo where I used a header/footer project, places a TLayout in the upper half and the map in the lower half and a speedbutton in the header. The speed button event has the following code (which works fine on Android)
As I understand the webgmap must be created on the mainform, right ?
The reason why I'm moving it around with the button is that in my "real" project that layout is on a TFrame, that is dynamically created.
So when I switch pages I just place TFrames inside a TLayout on the mainform. At some frames I use the WebGMap, which is created on the mainform and then made invisible. If the frame is created that uses the map, I change the parent, the alignment and make it visible. In Android that works fine, but win32 gives me that error.
I'll try your solution, but I think it was made clear that i can't use webgmap that way directly on another form that is not the mainform
